摘　　要：本文基于面元法理论对桨后贝克舵的水动力性能进行了研究。首先结合空泡水筒试验的试验结果检验了面元法程序的计算精度及可靠性,并将面元法计算所得水动力系数绘制成敞水性能曲线,对两种桨舵系统的水动力性能进行比较分析得出贝克舵的节能效果。然后改变桨与贝克舵之间的距离考察其对节能效果的影响,并与实验结果对了对比,结果显示,桨舵间距越大,桨舵系统的效率也就越高。Based on the theory of the surface panel method, the paper studies the hydrodynamic performance of the beeker rudder after propeller. First, combining the experimental result of the cavitation tunnel test, the calculation accuracy and reliability of the surface panel method process are inspected The hydrodynamic coefficients obtained by the calculation of the surface panel method are plotted into the open water performance curves. By comparing the hydronamic performance of the two propeller-rudder systems, the energy-saving effect of the beeker rudder is obtained By changing the distance between propeller and rudder, the influence of the distance change on the enengy-saving effect is observed It is also compared with the experimental result, The comparing result shows that the larger distance between propeller and rudder, the higher the efficiency of the propeller-rudder system.
